This patent pending full-flow spin-on oil filter adapter allows for use of a conventional spin-on oil filter, rather than requiring the use of expensive and inferior replacement cartridge-style filters. This makes changing your oil a much simpler task. No longer do you have to handle changing out the cartridge, worry about contamination of the oil filter housing, or thinking you have cross threaded the cheap plastic filter housing since they don 't fit all that well. We 've also chosen a filter size that is easily found at any local auto parts store for a fraction the price of the original filter. Our spin-on oil filter adapter makes oil changes easy again! Includes an oil filter, filter adapter and install tool, magnetic drain plug, and an extra drain plug washer- such a value! This kit can use the K&N performance gold oil filter rhp1007.
